The bad-word list now comes from the ReSkate backend's Words page, in the same /api/v1/steam-ids answer the game and servers already read. It has two lists: filtered words, and words not allowed in chat at all. Until the backend has any words the built-in list stays in use; once it does, its lists replace the built-in one. Filtered words work as before: masked for players with the chat filter on, and not allowed in server or lobby names. Words not allowed at all are filtered the same way, and a chat message with one is not passed on. Its player is warned each time, and after three warnings the next one gets them kicked. Dedicated servers: new players setting word_warnings (default 3, 1 to 10, 0 switches the rule off). The count lasts while the server runs, so a kicked player who joins again is kicked at their next one. Party chat and commands are checked too, and each warning and kick is logged under [words]. The lists are read whenever global bans or word warnings are on. Player lobbies: the host's game applies the same rule to its guests, with three warnings.
